 ### Package Versioning
 Keeping track of different versions of the buildpack can be difficult. To help with this, the rake `package` task puts a version discriminator in the name of the created package file. The default value for this discriminator is the current Git hash (e.g. `cfd6b17`). To change the version when creating a package, use the `VERSION=<VERSION>` argument:
